Material Processing Process Of Plastic Single Screw Extruder

In the process of fastening bolts of single screw plastic extruder, the bolt is deformed due to tensile stress and its restoring stress is tightly connected with the sealing part of it, which is lengthened at any time, the partial tensile deformation becomes permanent deformation, and the recovery stress is reduced, resulting in stress relaxation and torque landing. Therefore, the bolt loosening phenomenon, causing the thread of sliding wire wear, serious or even the fastening parts of the screw damage.Plastic Single Screw Extruder

As a single screw plastic extruder for metal material, high hardness, in the production process by vibration and other composite forces, resulting in the formation of gaps in the parts, causing wear. Traditional repair methods are surfacing, thermal spraying, brush crossing, etc. however, there are some drawbacks in several methods: surfacing will make the parts surface to a high temperature, resulting in deformation or crack of parts, affecting the size of precision and normal use, serious will also lead to fracture; electric brush Watanabe Although no heat effect, but the thickness of the layer can not be too thick, serious pollution, The application has also been greatly restricted.Plastic Single Screw Extruder

Screw extruder Because of its simple structure, good value for money, high production efficiency characteristics, has been plastic pipe, sheet, sheet, profile and other molding processing the most important equipment. With the continuous progress of technology and people's familiarity with the progress of the screw, a variety of different types of extruder structure has been published. Twin-screw extruder market is unusually hot, relatively speaking, single screw has been in a quiet state. However, as a basic plastic processing equipment, single screw extruder has the advantages of simple structure, low cost and greater design flexibility. Various kinds of special single-screw extruder have been paid attention to.Plastic Single Screw Extruder

As the single screw extruder occupies a small space, it becomes more and more almost the only equipment used in the field of compound processing and blow moulding film. Single screw extruder technology has become an important part of extrusion processing market. The twin-screw extruder includes a parallel twin-screw extruder and a conical twin-screw extruder.Plastic Single Screw Extruder 

Parallel twin-screw extruder has the same direction and different direction. In recent years, with the rapid development of domestic electronic appliances, communications, automobiles and other fields, the market demand of material modification and blending technology has increased greatly.Plastic Single Screw Extruder
